Miyazaki creates a world with it's own politics, history and lore. and none of them is has a decent explanation that we would otherwise get if we read the manga, many of his other films also avoid these explanations, but they were never necessary, unlike this one.
this lack of explanation makes moments like the rebirth of the Giant Warrior and Nausicaä walking on a field of gold have very little impact
the characters are not really worthy of attention, except for Nausicaä, she actually has personality traits, however, that is not necessarily good.
our heroine embodies Miyazaki's views on enviromentalism, war, and other subjects. in a very naive and idealistic way, which i dislike quite a lot.
Momonoke Hime is just superior in pretty much all aspects.
PS: gave it +1 point for the soundtrack. Joe Hisaishi is a legend. and the OST is definetly better than the movie overall.
